Abstract Cyclohexanol and 1-methyl-1,2-cyclohexanediol were produced via the hydrotreating of guaiacol, using new hydrotalcite-based nickel (HT-Ni-R) and cobalt (HT-Co-R) catalysts.. Guaiacol is the most representative model compound for lignin-derived bio-oils. Catalysts were prepared by co-precipitation of the metals (Mg-Al, Ni or Co) …
